摘要： In one illustrative example, a technique in a mobile communication device which is operative in a wireless communication network for Push-To-Talk (PTT) communications involves receiving, at the mobile communication device, presence information associated with at least one other mobile communication device, the presence information including at least one of a current availability indication or capability indication; and buffering a PTT communication prior to its transmission from the mobile communication device based on the presence information. The current availability or capability indication may be an automatic answering indication or a media capability indication, as examples.

摘要： In one illustrative example of the present application, a mobile communication device has one or more processors, a wireless transceiver adapted to provide communications through a wireless communication network, and a buffer memory for use in buffering a Push-To-Talk (PTT) communication from the mobile communication device. The one or more processors are operative to produce a mobile device indication message which indicates the mobile device's support for buffering of the PTT communication. This message is transmitted by the wireless transceiver to a PTT service entity through the wireless network. The one or more processors may be further operative to receive, from the PTT service entity through the wireless network, a network indication message which instructs the mobile device whether to use buffering for the PTT communication. The mobile device may use the buffer memory for the buffering of the PTT communication based on the network indication message from the PTT service entity.

摘要： An apparatus and method for telephony tone signal and character code generation for QWERTY keyboards includes a QWERTY style keyboard, a processor and a keyboard mode control software module. The QWERTY style keyboard has a plurality of letter keys, wherein each letter key is configured to generate a unique input signal. The processor is coupled to the keyboard and is configured to convert each unique input signal generated by the letter keys into a character code and/or a telephony tone signal. The keyboard mode control software module operates on the processor, and controls whether the processor converts the unique input signals from the letter keys into character codes or telephony tone signals.

摘要： A method includes steps, performed by a wireless device for accessing a wireless network through network base stations. The steps include selecting a reverse link cost metric from a list of reverse link cost metrics. A reverse link cost is determined according to the selected reverse link cost metric. A plurality of base stations are partitioned into a plurality of candidate base stations and a plurality of excluded base stations. The plurality of base stations are substituted with the candidate base stations, thereby reducing the cardinality of the plurality of base stations by the cardinality of the plurality of excluded base stations. A candidate base station is selected from a plurality of the base stations. A probe signal is sent at the reverse link cost to the candidate base station. A response from the candidate base station is waited for within a timeout period.
